In a classroom, if 6 students per bench are assigned to accommodate all students, one more bench will be required. However, if 7 students are accommodate per bench, there would be a space left for 5 students.What is the number of students in the class ?
A. 30
B. 45
C. 42
D. 72

• 
  Let the number of benches in the class be x.
  Then, 6(x + 1) = 7x - 5
  x = 11.
  Hence, number of students in the class = 6 ( x + 1)
  = 6 x 12
  = 72.
